Uptime.com is a well-established technology company specializing in website and API uptime monitoring services. Founded in 1994, it offers a comprehensive SaaS platform with advanced monitoring capabilities including synthetic monitoring, real user monitoring, status pages, and private location monitoring. The company targets businesses and IT teams requiring reliable uptime and performance visibility, positioning itself as a trusted provider with enterprise-grade features and a large global observability network. The website reflects a mature digital presence with professional design, clear navigation, and extensive content describing its services and solutions. Technically, the website leverages modern web technologies such as JavaScript, Google Tag Manager, service workers, and HubSpot CMS. It is hosted on Amazon AWS infrastructure, ensuring scalability and reliability. The site is optimized for mobile devices and accessibility, with good SEO practices and fast performance. Analytics usage is moderate, employing Google Tag Manager and PostHog for real user monitoring, with appropriate privacy compliance measures including cookie consent and GDPR-aligned policies. From a security perspective, Uptime.com demonstrates a strong posture with HTTPS enforcement, domain status protections, and SOC 2 Type II and FSQS certifications. However, there is room for improvement by enabling DNSSEC, publishing a security.txt file for vulnerability disclosure, and enhancing visible security headers. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data confirms the domain's legitimacy, with a long registration history consistent with the company's claims. Overall, Uptime.com presents a low-risk profile with a professional, secure, and compliant online presence. Strategic recommendations include enhancing DNS security, formalizing vulnerability disclosure, and increasing transparency around incident response contacts to further strengthen trust and security culture.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Uptime.com operates in the competitive website and API monitoring market, leveraging its long-standing domain and strong certifications to differentiate itself. Its business model is subscription-based SaaS with add-ons and professional implementation services (UPro!). The company targets a broad range of industries including ecommerce, finance, education, SaaS, and enterprise sectors. Its competitive advantages include a large global monitoring network, comprehensive integrations, and advanced alerting capabilities. The presence of multiple trust badges and high Net Promoter Scores indicate strong customer satisfaction and market credibility. The company maintains an active content strategy with blogs, FAQs, and detailed product documentation, supporting customer engagement and lead generation. Partnerships and affiliate programs further extend its market reach.

Security posture

Uptime.com exhibits a mature security posture with HTTPS enforced site-wide, domain registration protections (clientDeleteProhibited, clientTransferProhibited, clientUpdateProhibited), and SOC 2 Type II compliance. The platform uses service workers for analytics and employs real user monitoring scripts securely. No exposed credentials or vulnerable libraries were identified in the HTML content. Privacy policies and cookie consent mechanisms are in place, supporting GDPR compliance. However, the absence of DNSSEC and a published security.txt file are gaps in best practices. Incident response contact details are not explicitly provided, which could be improved for transparency. Overall, the security culture appears robust but could benefit from formal vulnerability disclosure and enhanced security headers.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  3. Add or enhance HTTP security headers such as Content-Security-Policy and X-Frame-Options.
  4. Include explicit incident response contact information on the website or trust center.
  5. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.

Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
